How to Calculate Schengen 90/180 Day

What is Schengen 90/180 Day?

The Schengen Days Calculator tracks how many days you have spent and how many remain under the 90/180 rule for the Schengen Area. Non-EU nationals can stay a maximum of 90 days within any rolling 180-day period, and exceeding this limit can result in fines, deportation, or entry bans.

Formula

Days Used = sum of days present in Schengen zone within the 180-day window ending on the reference date; Days Remaining = 90 - Days Used

D_used: Days Used (days) — Total days present in the Schengen zone within the 180-day lookback window
D_remaining: Days Remaining (days) — 90 minus days used — the maximum additional days you may stay
W: Window (days) — The rolling 180-day period ending on the reference date

Step-by-Step Guide

1Enter your travel dates (entry and exit) for all Schengen zone visits in the relevant period
2Choose a reference date (today or a future planned entry date)
3The calculator looks back 180 days from the reference date and counts all days spent in the Schengen zone
4It subtracts the used days from 90 to show how many days you can still stay
5For future trip planning, it shows the earliest date when additional days become available as older stays roll off the 180-day window

Worked Examples

Input

Stayed 30 days (Jan 1 - Jan 30), reference date March 15

Result

30 days used in the 180-day window. 60 days remaining until June 30 (when Jan days start rolling off)

Input

Three trips: 20 days in Jan, 25 days in Mar, 15 days in May. Reference date: June 1

Result

60 days used. 30 days remaining. After June 30, Jan days expire and 20 more days become available

Common Mistakes to Avoid

✕Thinking the 90 days reset every 180 days like a fixed period — the 180-day window is rolling, meaning it shifts every day based on your reference date
✕Forgetting that both the entry and exit days count as days present in the Schengen zone
✕Not realizing that all 29 Schengen countries share the same 90-day counter — days spent in France reduce your available days in Germany, Italy, and all other Schengen states
✕Confusing Schengen zone membership with EU membership — some EU countries (Ireland, Cyprus) are not in Schengen, while some non-EU countries (Norway, Switzerland, Iceland) are

Frequently Asked Questions

What happens if I overstay the 90-day limit?

Consequences vary by country but can include fines, deportation, and entry bans ranging from one to five years. Some countries are stricter than others, but overstaying is recorded in the Schengen Information System and affects future visa applications for all Schengen states.

Do transit days at Schengen airports count?

If you pass through passport control and enter the Schengen zone, that day counts. Airside transit (staying in the international zone without clearing immigration) does not count, though some nationalities need an Airport Transit Visa even for airside connections.

Does the new ETIAS system change the 90/180 rule?

No. ETIAS (European Travel Information and Authorisation System) is a travel authorization requirement for visa-exempt nationalities, but it does not change the 90/180-day stay limit. You will still need to track your days the same way.

Can I reset my days by leaving for one day?

No. Because the window is rolling, leaving for a single day does not reset anything. Your previous stays within the 180-day lookback period still count. You only regain days as older stays fall outside the 180-day window.
